preenfm2 and preenfm3 / Re: New filters
« on: August 27, 2019, 04:53:32 PM »
@Toltekradiation all the stuff is great, it really adds a lot to the richness of the FM synthesis
Haven't dug really much deep in all the uses (although my PreenFM2 is always on in my spare time, since you made these additions :-) ), but these are some experiences so far
- Txr1 and Txr2: seems just like adding some noise to the signal? Of course the filters will behave differently with different signals that are put through, so I believe the type of the source sound is also important.
- Can the Mix parameter (generally) be replaced to some filter changing function? (like eg. LPx1 that besides Frequency the other parameter changes the xor amount). I think these kind of effects are not like eg. Reverb/Delay or similar that dry/wet ratio is that important.
- Is it possible to implement algorithm for Notch type effects (inverse of Band-Pass, that it just removes the Frequency)
You are right about the mixing of the 4 instruments, it can really make a difference with the filtering. I also know that the PreenFM2 architecture is a bit limited in this regard, as it acts just at the end of the signal-chain as a per-channel filter/effect, although modulatable by the Modulation matrix.
I wouldn't mind to have a lot of filters, why not :-) Just if some patches are saved with some effect, and they got replaced in the meantime, they will probably get back to the default, or switch to some other type.
As for the Chorus, and modulation effects, I know the trick of slight detuning, it is also very nice to detune a bit the modulator in comparison to the Operator, adds nice phasing effects that can turn to some waveshaping if modulated to more extremes. The FM is a great system for sound-mangling :-)
